Objective: This study was to discuss the influence of multi-year altitude training on the biochemical function and specific aerobic capacity of the Chinese national elite open weight woman athletes and to explore the law. Method: Organise tracking test of 12 Chinese rowing open weight woman Olympians’ function state in the past 3 years’ altitude training camp. Result: 1 The lactate threshold power is lower during the altitude training than that on the sea level(P<0.01); compared with before altitude training camp, the lactate threshold power increased significantly after altitude training camp, (P<0.01); it was observed, with horizontal comparison of the past 3 times altitude training, that the lactate threshold power increased annually, and increased most in 2008 particularly. 2 During the altitude training camps in the past 3 years, the body weight tended to decrease but there was no significant difference compared with on the sea level. The body fat percentage increased to the highest point in the latter part of the altitude training, while the lean body mass decreased to the lowest point in the same period, and increased again significantly after the altitude training camp(P<0.05). 3 During the altitude training camp, 6km Ergometer performance went down clearly; the best performance appeared in the 4 th week of the altitude training camp. 4 With no clear difference in Hct index, for open weight woman athletes, the HB level had a negative correlation with 6km Ergometer performance (Pearson correlation is -0.952, P<0.05); The 4 th week of the altitude training camp saw the peak HB value and the best 6km Ergometer results. Conclusion: 1 The study of the influence of altitude training on the lactate threshold power indicates that altitude training can significantly improve rowers’ aerobic capacity. 2 the environment of altitude led to a faster muscle decomposition, so during the altitude training, the body weight of open weight woman athletes dropped clearly. 3 In this study, after the altitude training, the Hb level had a negative correlation with 6km Ergometer performance and the aerobic capacity came to the highest level in the 4 th week after the altitude training camp.

The main indexes include Lactate threshold power, Body weight and fat%, 6km ergometer performance and Hb level during and after the altitude training. 3 RESULTS 3.1 The lactate threshold power The lactate threshold power is lower during the altitude training than that on the sea level (P<0.01); compared with before altitude training camp, the lactate threshold power increased significantly after altitude training camp, (P<0.01); it was observed, with horizontal comparison of the past 3 times altitude training, that the lactate threshold power increased annually, and increased most in 2008 particularly.
